Quoted a Roof and Found Asbestos? A Straight-Up NZ Guide for Roofing Companies to Get It Right

Quoted a Roof… Then Found Asbestos? Here’s How Roofing Companies Should Handle It (Without Blowing the Job Up)

It happens more often than anyone admits.

You quote a roof.
Everything lines up.
Then someone says, “That looks like asbestos.”

Suddenly the job goes quiet. The client panics. Your margin’s at risk. And the wrong move can land you in front of WorkSafe.

This guide walks roofing companies through exactly what to do when asbestos shows up, how to protect your business, and why working alongside a professional asbestos removalist is usually the smartest commercial decision you’ll make on that job.

Step 1: Know What You’re Looking At (and Why It Matters)

If the roof:

  • is corrugated fibre-cement

  • was installed before the late 1990s

  • has a chalky or fibrous edge when damaged

  • is common on garages, sheds, or older homes

Assume asbestos-containing material (ACM) until proven otherwise.

The critical point: 👉 Once asbestos is known or suspected, you cannot “carry on carefully.”

From that moment, you have legal duties — even if you’re “just the roofer”.

Step 2: Stop Before You Touch Anything

This is where many roofing companies come unstuck.

Do not:

  • remove a single sheet

  • drill, screw, or cut through roofing

  • pressure wash

  • “tidy up” broken edges

The second asbestos is disturbed, fibres are released — and responsibility attaches to whoever disturbed it.

That includes subcontractors.

Step 3: Understand Your Legal Position as a Roofer

In New Zealand, roofing companies are PCBUs under:

  • Health and Safety at Work Act 2015

  • Asbestos Regulations 2016

This means:

  • you must not expose workers or others to asbestos

  • you must ensure asbestos work is done by competent, licensed people

  • you cannot ignore known asbestos and proceed anyway

“No one told us” is not a defence once it’s identified.

Step 4: Be Clear With the Client — Early and Calmly

Clients usually panic because trades panic.

What you should say (plainly):

  • asbestos has been identified or is suspected

  • the roofing work can’t legally proceed until it’s dealt with

  • this is normal for older roofs

  • there’s a clear pathway forward

When you handle this calmly, you look professional — not difficult.

Step 5: This Is Where a Professional Removalist Saves the Job

This is the fork in the road.

Option A:
You walk away and lose the job.

Option B:
You try to handle it yourself and inherit legal risk.

Option C (the smart one):
You partner with a licensed asbestos removalist.

Working alongside PropertyHelp Ltd allows you to:

  • keep the roofing contract alive

  • avoid asbestos exposure risk

  • meet your legal obligations

  • protect your workers

  • protect your reputation

Good removalists don’t compete with roofers — they enable them.

Step 6: How a Roofer + Removalist Workflow Actually Works

A professional asbestos removalist will typically:

  1. Confirm the asbestos material

  2. Determine Class A or Class B requirements

  3. Prepare the Asbestos Removal Control Plan (ARCP)

  4. Isolate the work area

  5. Remove asbestos roofing safely and intact

  6. Dispose of it at an approved facility

  7. Provide documentation and clearance

Once that’s done:

  • the roof is safe

  • your crew can install immediately

  • the client gets continuity

  • you look organised, not reactive

Step 7: Why DIY or “Careful Removal” Hurts Roofing Companies

Roofers who try to “just remove it gently” often face:

  • WorkSafe complaints

  • neighbour exposure claims

  • delayed projects

  • insurance issues

  • black marks with councils and PCs

Even worse — future clients remember who caused problems.

Partnering with a removalist costs less than one enforcement notice.

Step 8: Quoting Smarter Next Time

Experienced roofing companies now:

  • flag asbestos risk early

  • build provisional clauses into quotes

  • have a go-to removalist partner

  • avoid surprise costs and delays

That’s how businesses survive in older housing stock areas.

Why PropertyHelp Ltd Is a Practical Partner for Roofers

PropertyHelp Ltd works alongside roofing companies to:

  • remove asbestos roofing legally

  • minimise downtime between removal and install

  • handle ARCPs, disposal, and documentation

  • keep roofers out of enforcement trouble

They understand site sequencing, weather windows, and the reality of roofing margins.

Final Word: Asbestos Isn’t the Problem — How You Handle It Is

Asbestos roofs are common.
WorkSafe investigations are optional — depending on your choices.

The roofing companies that last:

  • stop when asbestos appears

  • bring in professionals

  • keep the client informed

  • get back to roofing fast

That’s not over-compliance.
That’s commercial survival.
